A highly substituted and fluorescent Isoindole has been used in a bilayer type of organic electroluminescent device with either PVK or Alq3. The best results (maximum luminance > 6000 cd/m2, apparent quantum yield at max luminance of 1.1%, and a low threshold voltage of 4 V) are obtained for the combination: anode/Isoindole/Alq3/cathode. These devices are characterized by the Alq3 electroluminescent spectrum. The role of Isoindole is that of a hole transport material. This is in agreement with the reversible character of Isoindole electrochemical oxidation and the stability of the Isoindole cation radical in solution. Lower maximum luminances (approx. 30 cd/m2) are obtained when Isoindole is replaced with Polyisoindole, a polymer containing the Isoindole in its backbone.
